Hulkenberg smiled: “‘Test champion’ gives me nothing. But I am in good shape.”

Vettel continued to Kleine Zeitung newspaper: “This year everything is closer together”, he said, after his teammate Mark Webber admitted there is “no question” Red Bull needs to keep working on the pace of its new RB8.

According to Die Welt newspaper, Vettel continued: “Most of the competitors are difficult to assess. It’s the same old game.”

He is referring to unknown fuel levels, tyre age and differing approaches and programmes — and teams’ deliberate sandbagging or ‘show-run’ efforts.

“I never paid too much attention to direct comparisons on headline laptimes,” insisted David Coulthard, “but on the longer runs you can start to build a picture.”

Williams engineer Mark Gillan told Auto Motor und Sport: “It seems as though the entire field has moved much closer together. It will be a tough fight.”

An early assessment of the pecking order might have Red Bull and McLaren at the front, and Mercedes and Lotus possibly ready to join the fight.
